Background technology
In the technological process of water treatment field and chemical industry and refrigeration industry, exist evaporation and two kinds of heat transfer process of condensation simultaneously.At present their process equipment all is evaporimeter and condenser two parts that work alone usually, couples together with the flow process pipeline.Especially in the pressure steam distillation method that the desalinization water treatment field adopts; Its cyclic process of adopting is the top of squeezing into exhausted water through liquid pump spray-type evaporator; Waste water rely on gravity from the process heat absorption evaporation that falls; The water vapour that is evaporated relies on compressor to improve pressure and temperature, enters into condensing heat exchanger then and is condensed into pure water, and water vapour condensation liberated heat is used for heating the energy that newly advances exhausted water and its evaporation is provided simultaneously.This wherein adopts the spray-type evaporator pipeline also is the vapour-liquid condensing heat exchanger when serving as evaporimeter, accomplishes the evaporation of exhausted water and the condensation process of clean water steam simultaneously.Pressing the evaporimeter of steam distillation process using at present all is that traditional evaporimeter separates the pattern that is connected with pipeline with condenser with condenser.Because when spray-type evaporator spray liquid can not evaporate fully, unevaporated drop falls in the liquid return tank, thereby has wasted the pump merit of raising its gravitional force, the loss that has brought merit.And the circulation of the plumbing drain of the traditional condenser that adopts at present, the system that makes needs the sewage (waste water) recirculating pump (general internal circulating load is 1000 times of evaporation capacity) of big flow.This circulating pump need consume a large amount of pump merits, makes whole water treatment system be difficult to obtain higher system efficient, and just this reason makes and presses steam distillation to follow the method for treating water of nobody shows any interest in into a kind of inefficiency.
Pressing steam distillation is a kind of water technology of physical method, has and does not add chemical agent, and compactedness is high, takes up an area of and lacks a kind of water technology that the feature of environmental protection is high.In order to improve the cycle efficieny of pressing the steam distillation method for treating water, make it become a kind of competitive method for treating water, the present invention proposes board-like evaporimeter of a kind of combination wheel and condenser.This method can improve the evaporation efficiency of pressing in the steam distillation and the heat exchange efficiency of condenser significantly, makes the cycle efficieny of whole system improve greatly.This knockdown evaporimeter adopts the evaporimeter (quantity of rotating disk is confirmed according to the scale of evaporation capacity) of one group of rotating disc type; Condenser adopts plate type heat exchanger; Closely arrange with little intervals between the cold plate of evaporating pan and condenser; Thereby make evaporimeter and condenser be combined into one, saved the effluent cycle loop, saved a large amount of circulating pump merits.In board-like evaporimeter of combination wheel and condenser, accomplish the evaporation and the water vapour condensation heat release heating sewage of sewage simultaneously, make sewage obtain the process of evaporation heat.Adopt board-like evaporimeter of this combination wheel and condenser structure; Can be so that evaporimeter obtains very high evaporation efficiency; Simultaneously also make condensing heat exchanger that very high heat transfer coefficient is arranged; Thereby make overall system efficiency be greatly improved, make and press steam distillation to become a kind of method for treating water of greater efficiency, lay a good foundation for it moves towards practicability.
Summary of the invention
The purpose of this invention is to provide a kind of board-like evaporimeter and condenser structure of integral type combination wheel that be applicable to evaporation and condensation process.This structure comprises one group of disc type evaporimeter (1) of slow rotation (rotating speed is lower than per minute 300 to be changeed); And with the rotating disk plate-type condenser (5) of Boulez at interval; The liquid level of evaporated liquor (3) is positioned at disc type evaporimeter (1) Lower Half, and floods all plate-type condensers (5).The principal character of its structure is that the rotating shaft (2) of disc type evaporimeter (1) is higher than liquid level (3) a little; Plate-type condenser all is positioned at liquid level below, between the plate face of the card of subsurface disc type evaporimeter (1) and plate-type condenser (5) with closely-spaced tight arrangement.
The major advantage of the integrated high-efficiency evaporator-condenser structure of this evaporation of the present invention and condensation process is: the liquid of panel surface is all evaporated, even unevaporated drop also can be avoided in the spray-type evaporator drop to splash down and produce losses of potential energy.2) can be so that the flowing velocity of condenser surface remain higher state, thus the heat exchange of condensation tube bank and liquid strengthened, improved the heat transfer coefficient of condenser pipe greatly.3) board-like evaporimeter and the condenser structure of combination wheel omitted the closed circuit of liquid pool, saved a large amount of circulating pump merits.When 4) this structure is used for the evaporation of sewage disposal, can also reduce the speed of dirt through the plate face of plate-type condenser and " the wiper effect " of card in the fouling of evaporation card.5) plate-type condenser is equivalent to a subsonic speed diffusion chamber to condensed gas, thereby the pressure and temperature that needs condensed steam is raise, and has also improved its saturation temperature, more helps the condensation of water vapour.

The specific embodiment
To combine accompanying drawing that the present invention is done further detailed description below.
For evaporimeter; The card of disc type evaporimeter (1) is that resistant material is made (like stainless steel and titanium alloy steel etc.); The liquid that card has been carried in the liquid pool through rotation evaporates in the space on liquid level (3) top, controls the water imbibition and the disengagement area of rotating speed and evaporating surface well, can not let card that the liquid that splashes down is arranged; The liquid of panel surface is all evaporated; Even if unevaporated liquid is arranged, also will follow rotating disk and incorporate once more in the pond, the potential energy that has lost with regard to having avoided the spray-type evaporator drop to splash down like this.Condensation vapour gets into plate-type condenser (5) from inlet (4), and at the interior water that is condensed into, the wall through plate-type condenser passes to the liquid in the liquid pool to the heat of transformation of condensation process simultaneously, and condensation vapour liquefy condensed water is discharged from condenser pipe outlet (6).In the heat transfer process of condenser, the steam in the condenser is film condensation heat transfer at wall, have the very high coefficient of heat transfer, so the heat exchange thermal resistance of condenser wooden partition has just become to influence condensation vapour transmits heat in liquid pool main thermal resistance.Because the rotation (stirring) of disc type evaporimeter (2) card can make the temperature of liquid pool keep evenly so that the plate face of plate-type condenser (5) passes to heat evenly diffusion in liquid pool of liquid pool.In addition, because plate-type condenser has the effect of diffusion, make the pressure of condensed gas and its corresponding saturation temperature all raise, thereby be more conducive to condensation of gas.The card of rotary evaporator is rotated and the closely-spaced tight arrangement of condenser in the liquid level bottom simultaneously; Can be so that the moving speed of the plate surface current of plate-type condenser remains higher state; Thereby strengthened the heat exchange of condenser and liquid; Improved the heat transfer coefficient of condenser greatly, made that condensation vapour and the liquid of liquid pool in the condenser can carry out little temperature difference heat exchange.And this structure can also reduce the speed of dirt in the fouling of evaporation card through " the wiper effect " of condensation tube bank and card when being used for the evaporation of sewage disposal.
